Silver halide photographic material

Abstract

A silver halide photographic material having as essential photographic layers at least one photosensitive silver halide emulsion layer and at least one non-sensitive hydrophilic colloidal layer on a support is disclosed. At least one of said photographic layers contains fine oil globules at a density of 1 or more, and a hardener having at least three functional groups is incorporated in at least one photographic layer containing said fine oil globules and/or at least one photographic layer which is farther from said support than the photographic layer containing said fine oil globules.

What is claimed is:

       6. A silver halide photographic material according to claim 1, wherein said hardener is represented by the following formula (I): Formula (I):     R(SO.sub.2 CH═CH.sub.2).sub.n     (wherein R is an aliphatic, aromatic or heterocyclic residual group having an n-valency; and n is an integer of 3 or more.)   
     
     
       7. A silver halide photographic material according to claim 6, wherein the aliphatic residual group represented by R in said formula (I) is a hydrocarbon group having 1 to 12 carbon actoms or a hydrocarbon group having 1 to 12 carbon atoms connected to an atom selected from among oxygen (O), sulfur (S) and nitrogen (N) atoms or to a group selected from among SO 2 , CO, aromatic and heterocyclic groups. 
     
     
       8. A silver halide photographic material according to claim 6, wherein the aromatic residual group represented by R in said formula (I) is a phenyl or naphthyl group. 
     
     
       9. A silver halide photographic material according to claim 6, wherein the heterocyclic residual group represented by R in said formula (I) is selected from the group consisting of hexahydrotriazine, piperazine, tetrahydrofuran and imidazolizine. 
     
     
       10. A silver halide photographic material according to claim 7, wherein the heterocyclic residual group represented by R in said formula (I) is selected from the group consisting of hexahydrotriazine, piperazine, tetrahydrofuran and imidazolizine. 
     
     
       11. A silver halide photographic material according to claim 1, wherein the functional groups of said hardener are active halogen atoms. 
     
     
       12. A silver halide photographic material according to claim 11, wherein said hardener is a hardener represented by the following formula (II) or (III) or a partially hydrolyzed product of the compound represented by the following formula (IV): Formula (II): ##STR13## {wherein R 1  and R 2  are each a hydrogen atom or an alkyl group; and Y is an alkylene group having 2 or more carbon atoms, a cycloalkylene group, a phenylene group, a biphenylene group, a phenyleneoxyphenylene group, ##STR14## (wherein R 3  is hydrogen atom or an alkyl group; and m 1  and n 1  are each an integer of 2 or 3) or ##STR15## (wherein R 4  and R 5  are each a hydrogen atom or an alkyl group; and m 2  and n 2  are each an integer of 2 or 3}.   Formula (III): ##STR16## (wherein R 6 , R 7  and R 8  are each a hydrogen atom or an alkyl group; m 3  is an integer of 2 or 3; and n 3  is an integer of 1 or 2).   Formula (IV): ##STR17## {wherein m 4  is O or a positive integer; n 4  is a positive integer; X is an organic residue with a valence of (m 4  +n 4 ); and R 9  is a hydrogen atom or an organic residue}.   
     
     
       13. A silver halide photographic material according to claim 1, wherein said photographic layer is a photosensitive silver halide emulsion layer containing fine oil globules.
